Bambu Lab X/P AMS 2 Pro Upgrade Kit

If you bought an X1 Carbon, X1E, P1P or P1S as a standalone printer and now want multi-colour printing and active filament drying, the AMS 2 Pro won’t simply plug in. Those printers were built before the AMS 2 Pro existed, so they lack the dedicated power feed and the connector arrangement it expects. This upgrade kit closes that gap — it’s the official bundle of adapter, cable, buffer and tubing that turns a non-Combo X1/P1 into an AMS 2 Pro host.

It’s a screwdriver-and-cable-routing job, not a rebuild. Bambu Lab publishes a step-by-step installation walkthrough for the P1S and X1 series, and most owners have it running inside an hour. Once it’s on, you get four-slot automatic material switching, filament runout handling, and the AMS 2 Pro’s active drying chamber for PETG, PA and TPU that have been sitting out.

Why you’d want this

Key features

• Purpose-built for non-Combo printers. Designed for owners who bought the printer on its own and are adding an AMS 2 Pro later.
• Handles the power problem properly. The AMS 2 Pro draws more than the X1/P1 mainboard can supply, so the kit includes the AMS 2 Pro Switching Adapter as a separate supply rather than a risky splice.
• Filament buffer for single-AMS setups. The buffer takes up feed slack between the AMS and the extruder — the standard arrangement when you’re running exactly one AMS 2 Pro.
• Three tube lengths, three couplers. One 370 mm and two 550 mm PTFE tubes cover the printer-to-buffer and buffer-to-AMS runs on both the enclosed (X1C/X1E/P1S) and open-frame (P1P) layouts.
• Genuine Bambu Lab hardware. Same part numbers your printer’s firmware and Bambu Studio expect — no third-party adapter quirks.

What’s in the box

• 1 × Filament Buffer (note: Bambu Lab also sells an AMS Hub configuration of this kit for owners chaining multiple AMS 2 Pro units — the configuration we ship is [VERIFY])
• 1 × Bambu Bus Cable, 4-pin
• 1 × AMS 2 Pro Switching Adapter (power supply)
• 3 × PTFE Tube Coupler
• 1 × PTFE Tube, 370 mm
• 2 × PTFE Tube, 550 mm

Please note: the AMS 2 Pro unit itself is not included — this kit is the connection hardware only. If you don’t already own an AMS 2 Pro, add one to your order.

Before you install

Update your printer firmware first. P1 series firmware supports the AMS 2 Pro from version 01.08.00.00 onward (01.09.00.00 and later is recommended for full compatibility), and X1 series printers may need a microSD-card firmware update to recognise it. Bambu Lab’s guidance is to disconnect the AMS 2 Pro while flashing firmware, then reconnect it — updating the printer also updates the attached AMS.

Who it’s for

Hobbyists who started with a bare P1P or P1S and now want multi-colour prints without buying a whole new machine. Small businesses and print farms standardising older X1C units onto AMS 2 Pro so drying and material tracking work the same across every printer. Schools and makerspaces extending the life of existing X1/P1 hardware — a cable kit is a far easier purchase order than a new printer.
